The National Weather Service got a temperature reading of 3 degrees at the Boise Airport overnight, making Friday the coldest day in Idaho’s capital city since 2010.

The low temp at the airport on Thursday was 8 degrees — making that the coldest day in Boise since Nov. 25, 2010. That title only lasted one day.

This is how cold it is Friday — the estimated high temperature of 21 for the Boise area is colder than the average low temperature of 23 degrees for Jan. 4 over the last three decades, according to National Weather Service reports.

There are fluctuations all over the Treasure Valley and the lows can vary by several degrees, so it might have been slightly chillier in your neighborhood today than 3 degrees.

There should be one more frigid morning before a warmer air mass is expected to move into the Treasure Valley over the weekend. Saturday morning is expected to be like Friday morning — with temperatures in single digits, flirting with 0.

But the estimated low temp for the Boise area on Sunday morning is a balmy 19 degrees, according to weather service reports.

As chilly as it is, we are still 10 degrees above the record low temperature for the Boise area, which was -6 on Jan. 4, 1910, according to weather service reports.

The last sub-zero day Boise had was in December 2009, according to National Weather Service reports.

It should be clear and cold for the beginning of the weekend, with estimated highs in the low 20s on Friday and Saturday.

A system expected to move through the Treasure Valley early Sunday will bring some clouds and 20 percent chance of snow in the morning and party sunny skies in the afternoon, with an estimated high temperature of 33 degrees.
